Starcraft sounds like it may just be a bit too quick for him, he is getting on a bit
He plays a fair bit of total war, in various incarnations, do you think he could cope with Starcraft, sounds pretty hardcore.

It's a brilliant game. One of the top games of 2000-09. It looks great on the PC. It's one of the few "console-to-PC" ports where the developers went all-out to make it look much prettier than the 360/PS3 versions.
